LM2576SX-5.0/NOPB TI Voltage Regulators - DC DC Switching Regulators
The LM2576 is a SIMPLE SWITCHER® step-down regulator providing 3 A of output current with a fixed 5.0 V output, operating from 8 V to 40 V input. It features a 52-kHz fixed switching frequency and requires only 4 external components. The device includes thermal shutdown, current limiting, and an on/off control pin, with efficiency up to 82% typical. Packaged in a 5-pin TO-263 (SX) for surface mounting, it is standard for easy-to-use high-current step-down regulation requiring fixed 5-V output. Applications include 12-V to 5-V conversion in industrial controls, automotive electronics, and consumer equipment requiring 3-A capability.
